Attention: Global TPM team,

Hi,

I found PAN-301496 in PAN-OS 12.1.4 Addressed Issues.
https://docs.paloaltonetworks.com/ngfw/release-notes/12-1/pan-os-12-1-4-known-and-addressed-issues/pan-os-12-1-4-addressed-issues

Is this issue fix in PAN-OS 11.2?

Best regards,
MasaW

If you are running PAN-OS 11.2 (any h-release), the firewall probably still has the older DNS cache behavior with potential insufficiency for very large numbers of FQDN address objects.

To get the PAN-301496 fix for improved DNS cache capacity, you need to be on PAN-OS 12.1.4

Hi @MasaW ,

This issue was reported in PAN-OS 12.1 only.

As far as I know PAN-OS 11.2 is not affected.

Kind regards,
